Y The invention is directed more especially to means for regulating and for throwing or moving on and olf the impression in a rotary printing couple mechanism, and to a simple, effective and accurate mechanism of the: kind described which is operated by a single attendant from onev side of the pre-ss, butwhich has impression effecting andcon trolling and locking mechanism on both sides of the press to insure uniform action.

Other features and advantages of the' invention will be primarily referred toin connection. with the following detailed description of the invention. 4

Referring vnow 'in detaily to the embodiment of the invention, illustrated by way of emma@ .it a@ general frame of a printingpressis shown,

ljc'urnaledl. betwveen these frames in a snit-able journalhbboires 5, these parts being only y,C eiieraIlyshown. a

Cooperating with the form cylindeis impression cylinder its" shaft-,1,1 journaled in bearings in the press 1 and [As embodied, spia journal tests ratte' ,i3 are' prevista; fer are Staav a time; and aeree-fand mais entrainant-.t1 boXes are bushings 14 and 15, having flanges 16 andl? 'at their .respective inner'e'nds npon-which abuts shoulders upon the shaft.

1i. The' shaft 11 of th' impression cylinder onrnaled eccentrically `in these bllliings' to effen; the fnfovemet f the' Cylinder to and from impression.

Fixed to the bushings A14 and 15,"respec-4 tively, lat the outer ends and eiteri'oijl'y thereof, are geared sectors 20 and 21. The bushings and sectors' are connected together by suitable tiene, 'gaat asf keys', 2iand 22. itactio'n` sleeve 24 and a5 ne prefer-amy pitvidd encircling the shaft V11 Within the bushings 14 and 15, and preferably .having flanges 26 and27 r`on the ez'ter'n'ajl faces of therespective bearings.

The4 embodied form of means for operai-.- l'

ing the sectors' comprises pinions' 30 ma` 3i,

fixed respectively on the oppfo'site endsof a shaft- 32, extendingacross the press and j ournaled a't eitlier side in the press frames 1 and 2.A The pinions and their shaftl are fixed together by suitable Ine-ans such' as keys 33 and 34, and friction slee'v'esS' and 36 are provided about the shaft atits' bearings inthe press frame. 'A hfand'wheel 38 is fixed on one end of shaft 32 by suitable means,` such as a key 39, and is held in place by a ,nut and washer 40, screw-threaded on the end of the shaft.

The printing couple i is rotated' any.

suitable gearing, one gear wheel 42 being shown inl Fig. 2this wheel being fastened to the' reduced end of the shaft 11 by a key 43, a nut 44` being screw-threaded on to the end of the shaft.

Means are provided .for firmly clamping or locking the impression cylinder yin iinpress'ion position, and as embodied two'arms 54 and 55 are formed integral w1th`the-re spective sectors and extending upwardly.

therefrom. Each of these arms at the upper end thereof is provided with a boss 57 which has a central cylindrical aperture 58 and a transverse side aperture 59, to receive and cooperate with the locking device on the press frame about to be described. Each of these bosses is conoidally beveled about the cylindrical opening 58, on the exterior face of the arm, to cooperate in the clamping action of the clamping or locking device.

Referring now to the embodied form of the cooperating clamping device on the press frame, a cross member 64 is centrally longitudinally cylindrically apertured, and is fitted into and supported by similarly shaped apertures in the press frame members 1 and 2. The member 64 is shouldered at and abuts against inner finished faces on the frame pieces 1 and The members 64 extend out beyond the frame pieces 1 and 2 at either side of the press, and such protruding portions are externally screw-threaded, and nuts 65 and 66 are screwed thereon to firmly hold lthe device in place.

Mounted within the. central longitudinal cylindrical aperture in the member 64, and projecting ltherethrough and extending therefrom at either end, is a rod 69, which is centrally preferably of reduced diameter, and is journaled in the member 64 at either end thereof with interposed sleeves and 71. Y

`The rod 69 at one end thereof (left-hand end in Fig. 2), is provided with a head 74, having at its inner end a conoidal clamping or locking surface 75, adapted t0 cooperate with the conoidal locking surfaces on bosses 57. At its opposite end the rod 69 is reduced, this reduced portion having a screw-thread 76. A head 7 7vis internally screw-threaded and is screwed on to the screw-thread 76. The head 77`is provided at its Outer end with a neck 78 terminating in a hand-bar 79. it its inner end the head 77 is provided with a conoidal bearing or clamping surface 80, which Vcooperates with the corresponding portion of the boss 57, in the end of the arm 54.

I make my clamping or locking device fool proof so that no inattention or mistake by the attendant can result in damage to the parts of the locking device. Any suitable form of mechanism for accomplishing this may be employed.

In the embodiment of my invention illustrated, but to which my invention is not to be limited, I slot the member 64 providing it with the slots 90, 90, Figs. 2 and 3. The longitudinally movable rod 69 is also provided with a slot 91 within which is mounted the sliding key 92 which also slides in the slots 90, 90 in the member 64. A loose collar 93 is mounted to slide on the exterior of the member 64 and cooperates lwith the sliding key 92 and the fingers 94, 94, on said sliding key. On the member 64 is mounted a fixed coller 95 held in position by the set screw 96. Between this fixed'collar 95 and the loose sliding collar 92, I mount a coiled spring 97 which normally presses the loose collar 93, sliding key 92 and rod 69 to the left of Fig. 2, bringing the locking or clamping mechanism into the position shown in Fig. 3. I may also mount a second fixed collar 98'on the exterior of the member 64 by means of a set screw 99.

This fool proof locking or clamping mechanism insures that the longitudinally movable rod 69 will be moved to the left'of Fig. 2, and into the position shown in Fig. 3, by the action of the spring 97 and disengage the conoidal locking or clamping part from the arm 55, before the attendant can disengage the conoidal locking or clamping part 80, on the head 77, from the other arm 54 by unscrewing the head 77. The sliding key 92 extending through the slots 90, 90 in the fixed member 64 prevents the rod 69 from rotatingwhen the head 77 is rotated by the hand-turning-bar 79.

Impression-regulating means are preferably provided cooperating with the foregoing mechanism, and as embodied a screw rod 100 is screw-threaded into the press frame members 1 and 2 respectively, one end of this screw rod being adapted to ,abut against the journal box 12 or 13, at that end of the impression cylinder shaft 11. In an opening 101 in the frame, nuts 102 and 103 are screw-threaded on screw rod 100, and may be turned to position the screw rod to regulate the impression as desired, and then may be locked in such position.

I also preferably employ screws 104 `and 105 extending through the cap 106 and adapted to bear upon the journal boxes 12 or 13 and hold said journal boxes in any adjusted position determined by the adjusting screw 100, and nuts 102 and 103.

The manner of operation of the previously described mechanism is substantially as followsz- Y n In the operation of the device it maybe assumed to be in the position of Figs. 1 and 2, with the journal boxes 12 and 13 pressing against the corresponding positioning screw 100, and with the locking or clamping device for the arms 54 and 55 clamped or locked as shown in Fig. 2. In throwing olf the impression, the attendant unscrews the head 77, and, as he does so the spring 97 through the sliding collar 93 and sliding key 94 moves the rod 69 to the left of Fig. 2 and disengages the conoidal clamping surface 75 from the boss 55, see Fig. 3. Then, after the locking mechanism has been first released on the opposite side from the attendant, further unscrewing of the head 77 will disengage the conoidal locking surface 80, on the head 77, from the boss 54, as shown llO stones iii Fig. s. The hand wheel 3s' is their itatednin the clockwise 'direction in l', and the consequent rotation of bushings le and 15 will throw Qii the iiiipiessioieeiai will move cylinder 10' avvay'ly from cylinderf 3 by reason of theec'centric mounting in the bushings of theshaft 1,1. j 1 when it vis desired to bring eyuiidei i0 back to iiiipfessioii-,posiiioin hand-whales isprotated in the opposite direction, bringing the journal'hoxes i2' and 13 against their positioning, screws 10o, which securite-1y determine tiieinpressoii- Ai the saine time the bosses 57 on the respective 54 pass into operative relation vvith4 the clamping devices on vrod 6,9, the rod passing'L into fthe openings 59.' The operator then tiirns the Head 7T Whichcauses the rod 69 to move. to sie iight if rig. s and' enses-uieisekiii'g siiifiiees ic engageant the bosser Ai thesainetinie this places the spring'97 under tension'. Further rotation ott the head 77 will casse the iekiiig suffices .so t 'be firmly held `to the boss 57 on the arm 54, which vxiill thenV rrnl'y securethe' parts in position.
